LOS ANGELES --

A controversial blood test that could reveal your lifespan is about to hit the market.

Scientists say the test can show how fast someone is aging and estimate how much time they have left to live. The test measures structures on your chromosomes, which are believed to be an accurate indicator of the speed at which you are aging.

Medical researchers say the test has a lot of potential for catching disease, but could also easily be abused for unethical reasons.
